Say less is a quick way to tell someone you are already on board. It can answer a request, accept an invitation, or reassure a friend that you understand what they need. In a friendly exchange it usually means the message has landed, rather than asking the person to stop talking.
In a sentence
“You want a rematch after dinner? Say less.”
In other words: I understand, and I am ready for the rematch.
Original example written for the JANK guide.How to use say less
Tone matters. A warm say less can be agreement or reassurance; a curt delivery can sound dismissive. Use the surrounding conversation to tell whether the speaker is accepting a plan, offering help, or simply acknowledging the message.
